Car is idling low , base idle was reset at dealer about a year ago due to same problem , 5 min and 95 bucks , I read somewhere but can't remember where that it can be reset through the DLC by grounding a pin , if so which pin and where is the dlc on this car . Any help appreciated

The DLC is on the drivers side near the power distribution box-jumper TEN and GND then adjust it see below-also do the computer relearn

Is the DLC under the dash or hood , are the pins numbered for easy ID or do you have a pic . Thanks

Its under the hood next to the power distribution box-it will show the pins under the cover
